How old are
you, exactly?

The "Days" stat above shows your exact total days alive from your date of birth to today. The average person lives about 30,000 days. If you're 30, you've lived roughly 10,950 days. The live counter in seconds keeps ticking in real-time as you watch.

The Date Calculators panel shows the exact day of the week you were born. Fun fact: slightly more babies are born on weekdays than weekends in most countries, due to scheduled caesarean sections and inductions being more common on weekdays.

Once you enter your date of birth, the birthday countdown below your age shows exactly how many days until your next birthday. The counter accounts for the current year and correctly handles leap years.

Yes — enter any date of birth above. It works for any person, pet, or event. Use the Date Calculators panel to check age at any past or future date too.

Western astrology divides the year into 12 zodiac signs based on the position of the sun at the time of birth. Each sign covers a date range of roughly 30 days. Your star sign (sun sign) is determined purely by your birth month and day, regardless of the year.
